You probably already know this but you shouldn’t book an expedition cruise expecting to see or do something specifically other than the general “cross/ experience the Drake Passage”, “see icebergs” and “see penguins” (no specific species).
We did not see any Adelie penguin colonies, despite that species being quite common in Antarctica, even though we were on an 11 night cruise that had a longer stay in Antarctica proper.
That is, even if the colony is known to be in an area on your itinerary, you still have to have other stars align to actually see them, such as good weather, no ice and no other ships booked for that site.
